ata_probe_ent_alloc() had a temporary hack such that devm_kzalloc()
was used for allocation if devres had been previously initialized on
the device; otherwise, plain kzalloc() was used. This was to make the
code useable from both the old and devres-aware libata drivers during
transition. This hack made ata_sas_port_alloc() unable to determine
how the probe_ent is allocated, causing double free in some cases.
Remove the now-unneeded hack and make ata_sas_port_alloc() use
devm_kfree().

James, thanks for the diagnosis and please ack if this fixes the
problem.
Jeff, after James' ack, can you please verify this works with a libata
driver? Just loading and unloading a libata LLD should be enough.
I'm visiting my hometown for lunar new year's day, so I can't do it
till Tuesday.
Thanks.
